Convert Ounces-force to Pounds-force

1 ounce-force is 0.0625 lbf. One ounce-force is exactly 0.0625 pounds-force.

One ounce-force is 0.0625 pounds-force. To convert ounces-force to pounds-force, multiply by 0.0625; to go the other way, divide by 0.0625 or multiply by 16. The factor is exact rather than rounded: it follows from NIST Special Publication 811. A sixteenth of a pound-force.

Factors are entered by hand from NIST Special Publication 811 rather than derived from a units library, so the ones that terminate are exact rather than rounded.

How do you convert ounces-force to pounds-force?

  1. 1.Take the measurement in ounces-force.
  2. 2.Multiply by 0.0625 — that is how many pounds-force fit in one ounce-force.
  3. 3.To go back the other way, divide by 0.0625, or multiply by 16.

Worked example: 25 ounces-force to pounds-force

Formula
ozf × 0.0625 = lbf
Arithmetic
25 × 0.0625 = 1.5625 lbf
Answer
25 ozf = 1.5625 lbf

The factor is exact, so this figure is exact too — only the display is rounded.

What is an ounce-force?

A sixteenth of a pound-force. Spring tensions, switch actuation and small-motor specifications are given here.

What is a pound-force?

The weight of one pound under standard gravity, exactly 4.4482216152605 newtons. A pound of mass and a pound-force are different quantities that share a name, which is why this unit exists at all.

How many pounds-force are in an ounce-force?

One ounce-force is 0.0625 pounds-force, exactly. Going the other way, one pound-force is 16 ounces-force. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
